Mendelian Genetics Intro Flashcards
1
Q
What is a monohybrid cross
A
The mating of two parents who are heterozygous in respect to a gene
2
Q
What is Mendels 1st law
A
Law of segregation
The two alleles for each gene seperate
3
Q
What is mendels 2nd law
A
Law of independent assortment
Genes on non homologous chromosomes assort independently
4
Q
Outline the process of Mendels first law
A
Law of segregation
Locus with differing alleles on each gene
During anaphase 1, homologous chromosome pairs seperate
Telophase 2/cytokinesis of meiosis 2 , each gamete have one unreplicated chromosome and hence one allele
5
Q
Outline the process of mendels 2nd law
A
Independent assortment
As cell reaches metaphase 1, homologous chromosomes line up independently
Where R or r goes does not dictate where Y or y goes
